like why so weird design decision ? in space you only need an engine .. there is no air or pressure to harm the ship..
you can add more rooms , more cargo , more skin to the ship..
since the ship will never land on earth you can do what ever you want as long as you have enough man power and money ..
The ship is so bare-boned because every single gram of unneeded structure is a fuel penalty.
yet usa will build factories on the moon and crash asteroids on it with metal and other resources to build a space ship.
so you can live with out the weight.. since there is no gravity in space..
am i wrong?
about the "spheres" why not to use a "square" shape? there is no need to use aerodynamics in space so you can any shape you want..
why not to build it in another shape.. like a plate?
The fuel tanks are spheres to equally distribute the pressure of the condensed gasses they contain. It's not about aerodynamics.
(as a stationary space station i do understand the wheel which will create artificial gravity, )
the trip to mars will take only 2 weeks* with the new nasa engine ,
* 2 weeks - or 1 month.
so again i don't really understand the reason for such weird body structure .
you won't even need to build it strong since there is nothing in space that can harm the damn thing..
(unlike movies like "avatar" you won't travel in space for 6 years .. thats just a very stupid thing to do. )
please note that i am not a professional person so i obviously talk nonsense so don't take me too serious
Just because there is no air doesn't mean you can put as much mass on it as you want. All that mass needs to be pushed, atmosphere and gravity aside. It's simple Newtonian physics that the more mass something has the more force it requires to get it to accelerate at a certain rate, and that means more fuel, which is a limited resource that you don't want to waste in space. You can't build a ship without a certain level of structural integrity, it has to accelerate, which puts force on the ship.
On the subject of not wasting fuel, most ships would probably not be going as fast as possible to get to another planet because it saves so much fuel to accelerate to a certain point and then coast. Also, if you have an artificial gravity wheel, it's not going to work properly while you're accelerating because of the force going towards the rear facing wall.
Pretty sure cryosleep is not a thing yet.
It was not "stupid" for them to spend 7 years travelling to their destination in Avatar. The ship used a lot of theoretical technology to theoretically be able to make it in that time, remember, they didn't just go to Mars or something, they went to ANOTHER STAR, several light years away. They had to accelerate to 70% the speed of light to get there in that time in the movie. They had a shield because at that speed hitting a speck of dust is like hitting a large meteorite. Chances are if we ever go to another star it will take a lot longer than 7 years.
This sort of spaceship design makes a lot of sense, at least, as far as I know.
